Not normally in our wheel house, we took on some engine work in this 2006 Trailblazer SS AWD. The original 6.0 LS2 turned itself into a coffee table due to an oiling problem to one of the connecting rod main bearings.
The best solution we could conceive would be to yank the old engine out and procure a used motor. We did. Just so happens that the monster we found was another 6.0 with an iron lung strapped to it, blown to about 550hp at the crank.
Here are the disassembly photos thus far, more to come.
